Description
Technical Field
The invention relates to the technical field of environmental protection, in particular to a method for preparing a waste barrel cleaning agent from waste grease.
Background
With the development of social economy and industrialization, the problems of resource shortage and environmental pollution gradually float to the water surface. The waste packaging barrel (HW49) belongs to the hazardous waste of the kind of being infected with, and the hazardous waste kind that its bucket inner wall adheres to is more, and the composition is more complicated, in case handle improper, can cause serious environmental pollution, and then influences the sustainable development of whole ecology.
In order to solve the problems, Chinese patent (patent publication No. CN108504474A) discloses an IBC packaging barrel cleaning agent contaminated with hazardous wastes, which mainly comprises the following components: ethyl acetate, carbonate, dimethylformamide, dichloromethane and xylene. The cleaning agent has a good cleaning effect on IBC packaging barrels contaminated by hazardous wastes, but solvents such as dimethylbenzene, dichloromethane and ethyl acetate in the cleaning agent have certain toxicity, corrosivity, inflammability or/and nondegradability, and the solvents have high cost and low recycling rate, so that the cleaning agent does not have industrial production and application prospects.
Another chinese patent (patent publication No. CN113814246A) discloses a zero-emission waste barrel cleaning method, which adopts hydrocarbon compound cleaning solution, and sends the residue generated after cleaning into a cement rotary kiln for incineration disposal. Although the method has a good effect of removing organic oily stains, the current hydrocarbon cleaning agent has a high technical barrier and is difficult to realize industrial application in a short time, and the incineration disposal method has high requirements on equipment and high cost investment, and the generated harmful gas is likely to cause secondary pollution to the environment.
Yet another chinese patent (patent publication No. CN113563991A) discloses a waste packaging barrel cleaning agent and a cleaning process, wherein the cleaning agent comprises the following components in percentage by weight: 87-89% of aviation kerosene, 4-6% of isohexide, 6-8% of ethylene glycol monobutyl ether and 0.05-0.2% of oil essence. Although the method has universality, the aviation kerosene belongs to class A flammable liquid, the flash point is 38 ℃, and the fire explosion accident can occur due to the fact that the temperature of the cleaning liquid is too high after the aviation kerosene is continuously cleaned for a long time.
In conclusion, the existing cleaning agent for the waste packaging barrel has the problems of narrow cleaning range, low recycling rate, poor harmless level and the like, and directly causes serious environmental pollution and large cost burden in the waste packaging barrel treatment industry.
Disclosure of Invention
The invention aims to provide a method for preparing a waste barrel cleaning agent from waste oil, which solves the problems of narrow cleaning range, low recycling rate and poor harmless level of the existing cleaning agent.
In order to achieve the purpose, the technical scheme of the invention is as follows: a method for preparing a waste barrel cleaning agent from waste oil comprises the following steps:
s1, placing 20-120 parts of waste oil into a stirring tank, adding 0.05-0.5 part of salt and 50-100 parts of deionized water, stirring at 70-90 ℃ for 30-60min, standing, and filtering solid suspension;
s2, slowly adding 10-40 parts of methanol and 0.3-1.5 parts of alkaline catalyst into a stirring tank, reacting for 90-120min under heat preservation, performing vacuum pressure reduction dealcoholization and dehydration after the pH value reaches 9-10, performing settling separation, and decoloring by using a proper amount of adsorbent;
s3, adding 1-5 parts of ethylene glycol monomethyl ether and 3-20 parts of modified polysaccharide, slowly stirring by using a stirrer at the temperature of 65-80 ℃, uniformly mixing, diluting by using a proper amount of water, and mixing with spice to obtain the waste barrel cleaning agent.
Furthermore, the waste grease is one or more of frying waste oil, waste oil collected by a range hood or swill oil and swill oil discharged by catering industry.
Further, the salt is one or more of sodium chloride, sodium nitrite and ammonium chloride.
Further, the acid value of the waste oil and fat treated in the step S1 is not less than 0.5, the treated waste oil and fat, 0.1-1 part of sulfuric acid and 180 parts of methanol are added into a reaction kettle, heated to 105-150 ℃ under the protection of inert gas, stirred for 60-100min, and then cooled to 75 ℃.
Further, the inert gas is nitrogen or argon.
Further, the alkaline catalyst is one or more of sodium hydroxide, potassium hydroxide or sodium methoxide.
Further, the product of the settling separation in step S2 is mainly crude glycerin, which is used to replace the sulfuric acid solvent.
Further, the adsorbent is one or more of activated clay, activated carbon and diatomite.
Further, the modified polysaccharide is one or more of carboxymethyl chitin, carboxymethyl starch, carboxymethyl cellulose and carboxymethyl inulin.
Further, the perfume is one or more of citral, menthol, geraniol and rose essential oil.
Compared with the prior art, the beneficial effect of this scheme:
the cleaning agent mainly takes the waste oil as the raw material, has low cost, has the recycling property of changing waste into valuable, and accords with the strategy of national low-carbon economy, circular economy and sustainable development; the cleaning product prepared by the method has good low-temperature fluidity and good stability, has good effect of removing stains such as waste mineral oil, resin, dye and the like which are difficult to clean, and has a certain antirust effect on iron waste barrels; the cleaning process of treating waste by waste is matched, so that the problems of high stain residual rate and high rework rate in the prior cleaning technology can be well solved, the cleaned waste liquid can be recycled, the maximization of waste disposal and resource utilization is realized, and the social benefit and the economic benefit are good.
